"powermaster 15% "

Powermaster 20% only $15.00/gal....used to buy it by the case, so buy 3 gals. & get one free from this one particular hobby shop.

I still fly my Predator 60 or my XL Fury Expert a least three times a week. The Pred gets a easy two eight minute flights on a tank and the Expert gets two seven minute flights per tank (smaller tank). My 90 size machines get one eight minute flight per 21 oz tank - easy choice.

I also only fly 15% - just have to be more careful with the sticks. I am content to do old guy stuff and don't need the massive power of modern electrics (although I have a couple).

Up here (Northern Calif) 15% Powermaster is about $21/gallon at the only LHS. I know that not too long ago Powermaster sold fuel in 55 gal drums (don't know if they still do). While fuel is expensive, have you ever checked out what a round of golf costs now days? I rather fly...........

The older I get, the fewer things seem worth waiting in line for.

you can make your own fuel but if you want to bring it to market that's where it gets stupid $$$$$$ for business.

I prefer electric for the easy quick anytime of the day flights
I Like nitro when I have time.
Sometimes they don't always start as planned

for me it cost 38$ cdn a gallon about 9 flights on a 600N so it has to be a special weekend to be worth it for me.

spending time, paying attention

EPA
We can thank EPA for all these regulations and shipping for nitro fuel. I believe this was designed to stop nitro fuel to save our planet.

I mostly fly my OS105 powered Hirobo Freya and Turbulence V2. Although I find the OS105 unusual to tune compared to an OS32 or 50 Hyper head it is a far more satisfying than electric.

I have changed a lot over the past few years and now really enjoy the sound, smell and occasional tinkering that comes with real engines. Flying nitro is a far more visceral experience than electric. I rarely fly my electric models now as I really dislike the charging and find it annoying being restricted to just two flight as I don't have more that two sets of batteries and don't really want to buy any more.

Did I mention I hate charging batteries?

Electric!
I have nitros they just sit!
messy, sticky, noisy, expensive, etc.

Have you seen the price of fuel! Price of glow plugs!

Have you seen the prices of these engines!!!!! lol no thanks. They have priced themselves right out of selling nitro's as far as I'm concerned anyhow.

Electric batteries- take care of them and keep recharging them. You can't recharge your expensive gallon of nitro.

Electric motor- take care of them and maybe eventually put a bearing in them. No stupid expensive piston, ring, liner, rod maybe, crankcase if you crash hard and rip the muffler off, head if you blow it up really bad.

You asked! So that's my 2 cents I have left after buying all this stuff....lol

Yes fuel is expensive. It costs me $60/Hr to run my D3v2 and $40/Hr for my Freya.

Glow plugs expensive?? $5-$6 once in a while, hows that expensive.

Sticky? Only castor oil is sticky.

Lets face it, when it comes to glow powered helicopters, you either love them or hate them. I love them.

Btw this topic has been done to death over the years although I suppose it's interesting to see how people's opinions change over time.

I feel nitro's makes you a lot better of a pilot because you have to be smooth and easy on the pitch unlike electric helicopters.
That was true 5-10 years ago but thanks to the new high power nitro motors and FBL you can bang the sticks all day long with a nitro, you don't have to be nearly as careful on the sticks as you used to be. (you need to be able to tune a nitro though obviously).

You are correct in that nitro makes you a better pilot but only because of the fact you get more flight time, and not just per flight, I mean you can refuel in seconds and be back in the air again.

Electrics are great in up to 550 size.

My perfect 2 heli fleet would be a 500 electric and a 600 nitro. WHERE ARE ALL THE 600 NITROS?! Or even better 550 nitros! I would sell all my helis right this minute for a 550 nitro, belt driven tail and adjustable main gear ratio so you could choose from different engine sizes from a standard 50 or even 37 to a 120!

60% of the time, it works every time!

Well it looked like JR was about to release a 550EP and nitro but then it all turned pear shaped. Would be great if the new Hirobo 550EP would be released also in a 37-55 version.

I once had a Hawk Pro 30 size when I had put in the hyper 50 and the larger tank I was getting 15 minute flights.

I would still be flying it, if it were reliable enough

I was considering making a 30 size with a 600N but I don't think it would get the same flight times

I'll throw in my $0.02.

I started with Nitro in 2001 with a raptor 30 then converted to a 50, then upgraded to a 50 compass, and finally have been flying electric the last 3 years.

My 600 size Knight 50 3D converted to FBL with a YS56 would yield 14 minutes of non pitch concerned balls to the wall bashing flights.

That said, I had to deal with:

* Constant main engine bearing replacements (2, maybe 3 times a year). No its not the engine. OS 50 does it YS 56 does it. (Its the nitro content that sucks humidity into the engine and corrodes the chrome and steel dissimilar metals)
* Enya 3 glow plug replacement every 5-6 flights ($7 each).
* Muffler either coming loose, leaking and losing tune or the baffle failing after some years (hatori pipes are the sh!T).
* Fuel lines falling apart in the tank due to 30% nitro is just harsh. The engine cutting out in mid air (auto time)
* Fuel filter getting clogged by who knows what piece of dust in the carb and needing to tear it down completely.
* Binding carb barrel after a few years of use.
* VIBRATION everywhere (its a single piston engine folks).
* Hydro locked engine needing the starter from of a small block chevy to get it going (sullivan starter is all you will EVER need).
* Glow driver not charged and the need to drag out your whole field box as a backup to the flight line (thank RCATS for the best glow driver ever)
* Its cold today...2 clicks rich. Got warmer in afternoon...2 clicks lean. 90+ deg out ... 4 clicks leaner...Engine melts, new piston ring and sleeve.

With the electric Goblin 700 or 380. Plug battery in...fly.
Never touched an engine bearing or bothered with tuning once it was up and running. Flies the same every time.

You need to do your homework up front, but once you set it, its the same all the time. Don't have to worry about if its cold or hot out today.

Sure flight times are like 4-5 minutes of full power, but then I just bought more batteries. Meh.

At $40+ per gallon for 30% nitro, I think not anymore. I'll just burn out my remaining stash of $17 per gallon 30% nitro and put my nitro on the museum wall in my workshop once its over. She had a good run.

Times changed years ago for me. Long flight times are overrated. After 8 minutes of continuous flying, what do you do up there, hover, figure 8s? I'm fried after that.

Collective management is something neither nitro or electric has forced me to learn well.

Nope. Not going back for me. Batteries are whats holding long flight times back and they keep getting better and cheaper every year.

I did say
(you need to be able to tune a nitro though obviously).

No wonder you get 14 minute flights! The rest of us get 7-9 minutes, hardly ever replace a rear bearing and only change a plug every few gallons unless our muffler has come loose?!

As for fuel lines not lasting in the tank you need to refill the tank as soon as possible after a flight.

There is an art to looking after a nitro but there are only a few simple rules to follow and they become very reliable... almost as reliable as batteries, ESC's, power supplies and generators!

60% of the time, it works every time!

BTW, on another note.

I used love my JR 9303 transmitter with its metal case.

Hope your transmitter is not all plastic or you don't have a touch screen.

Try getting 30% nitro on your hands from going over to your heli, either from just touching the oil all over or from spill over during fueling, then grabbing your plastic transmitter.

Hint, it melts plastic.

It seems even transmitter manufacturers moved on from nitro, for the most part.

Even wonder why spray can paint jobs never worked on nitro helis. The nitro melts the paint off. Only real automotive 2 part clear will hold up.

Just some additional thoughts.

My YS56 was a rock solid engine. Still have it.

Tuned to perfection for the most power. It never ran hot after any of my flights. Beautiful engine for me.

The only time it had wonky tune was when the bearings would start to fail. Yes, you can hear it when it starts to go from the noise in the pipe as a higher pitch to it.

You guys can ask anyone on this forum. You could put in a bearing today and tomorrow it was bad. Luck of the draw or just the way it was. Look up all the talk from years ago about Boca bearings, Stainless vs Chrome vs ceramic, metal race versus phenolic, to after run oil or not, endless posts.

Anyone at the field that I know was proficient in tearing down their engine block, baking it in an oven and popping in a new bearing in no time.

But the fact that you have to do that is my point. Nitro engines are fickle things and if you say otherwise you are an apologist or a romantic.

The scorpion on my Goblin has gotten dabs of oil as required in the manual and other than that, no other service in the last 3 years. I could not say that about even the best nitro engine.

I dont know what your smoking
but I dont want any of it cause its not good stuff

I havent ever heard a bigger crock in my life about
glow powered engines

that or you and them other cheese heads up there
dont have a clue about tuning an engine (which is know doubt the problem)

ageing is manditory maturity is optional

Lets not get harsh and try and educate instead.
Hope your transmitter is not all plastic or you don't have a touch screen.

Your wrong about it melting plastic but kind of right about it melting (it doesn't actually melt!) paint but I have used the same old DX7 (JR radio basically) which is plastic for 10 years with nitro helis on 30% fuel and the paint is like new.

Maybe it was the fuel you were using that was causing all the problems if it was so acidic! Use Optifuel and never look at any other fuels ever again!

60% of the time, it works every time!
